Week 12 - Wifi shield is getting problem !

As salam..

Last two days, I had went to Shah Alam,
regarding on the problem of wifi shield.
The problem is like in this video :

I went back to Shah Alam to see Nik and
En.Azmi regarding on this problem.
What I found in solving this matter is :

Clicked the Terminal, for the Local echo and Local
line editting, clicked at the "Force on". Before this
it sets at "Auto". That is the reason why the problem
is happened that show in the video.

Then, you clicked open, it will be ready to type the
AT command.
Before that, we find out the IP address, gateway
and subnet. Below are some of pictures that show
the AT command. Which some of is ERROR,
and finally solved by searching in internet the right
command.

IP address is success

AT command of "AT+WAUTO.." is success

AT command of "AT + NAUTO.. " is success

Below is the AT command by looking on the 

tutorial of Putty I had :

AT command of Putty configuration

By looking on the pictures that had taken

and with the AT command, can see the different.

Some of AT commands are ERROR when type

in the Putty. So, the pictures taken are the right 

command. 

All that, by referring on this link 

http://www.dfrobot.com/forum/index.php?topic=515.5;wap2

When all the AT command is successful.

The wifi also success acted as a server.

But, other problem is come. 

It's not connected to the Arduino.

When looking on the post last week,

at the end, supposedly, the data that type 

in Putty, will be linked to the Arduino, 

but at this time, there is no connecting..

Error is found. We had tried to change the 

arduino uno, but still not connected. Searching in 

internet, if it has any solutions, but still no highlight

to solve the problem.

Finally, En.Azmi and Nik suggested, what if 

change to used a APC220 Radio Communication 

Module.The module is seems like a Xbee. 

Which a complete module with transmitter in receiver.

Here is the picture of 

APC220 Radio Communication Module.

Since just leave 2 weeks for the presentation,

This module also relate with transmit data to 

the laptop which can view directly by a clinician.

So I've decided to buy this APC220.
